SPECIFICATION forming partfof Letters Patent No. 729,814, dated June 2, 1903.-

Application filed September 30, 1902. Serial No. 125,421. (No model.)

To all whom, it may concern:

Be it knownthat we, FRANK VOIGTMANN, residing at Chicago, Illinois, and SILAS I-I. POMEROY, residing at New York, State of New York, citizens of the United States, have invented certain new and useful Improvements in Sheet-Metal Windows, of which the following is a specification.

This invention relates to improvements in sheet-metal windows, and refers more specifioallyto a sheet-metal window-sash of improved construction.

The salient object of the invention is to provide a more simple and efficient construction which may be formed by machine and with the minimum number of operations,thereby greatly lessening the cost of production and at the same time producing a better-finished tion of the glazing, either originally or when it becomes necessary to renew the same, may be accomplished with the utmost facility and in which the several members of the sash or frame may be originally assembled with the minimum amount of labor, to provide a construction which is fireproof in the highest degree attainable in a sheet-metal construction, and in general to provide a simple and improved construction of the character referred to.

To the-above ends the invention consists in the matters hereinafter described, and more ings, in which Figure 1 is a face view of a window-sash embodying our invention. Fig. 2 is a vertical sectional view taken online 2 2 of Fig. 1. Fig. 3 is a'horizontal sectional view taken on line 3 3 of Fig. 1, the central portion of the sash being broken out to reduce the size of the figure.

formed, so as to form a sash presenting a similar appearance on both sides. A salient feature of the present invention consists in form 'ingthe said sash face members 1 and 2 from single sheets of metal by means of suitable dies, so thatall seams at the junctures of the side stiles with the top and-bottom sash members are entirely obviated. Each sash face member is provided upon its inner margins with a die-formed molding or extension 3, which is struck up out of the general or face plane of the member and terminates at itsinner edge 4 in a plane parallel with but considerably removed from the outer face plane. This molding-like extension is in cross-sectional form arranged to extend obliquely inwardly and toward the center of the sash, as indicated clearly in the several cross-sectional figures, and is desirably corrugated or ornamental-shaped, as indicated at 5, so that the glazing is recessed or set back from'the face planes of the sash, as usual.

In the preferred construction illustratedin Figs. 1 to 3,inclusive, the inner margins of the face members are folded back upon themselves to form a double-thick flange portion 6 parallel with the outer face of the sash, the inner lap 7 of said double-thick portion being bent again at right angles to the general plane of the sash, as indicated at 8, to form the outer side of a channel, (designated as a whole 9,) which receives the edge of the glass 10. The two face members beingsimilarly Fig. 4 is a horizontal sectional view of one side of a sash of slightly-modified but reversely formed are arranged with their double-thick flange portions 6 at a distance apart approximately equal to the thickness of the glazing and with their angular flange portions 8 overlapping, as indicated clearly in Fig. 3.

The outer marginal sides of the sash-frame are formed, in the preferred embodiment of the invention, of members 11, 12, and 13 of channel shape in cross-section, the vertical side members 11 and the bottom member 12 being constructed to fit between the two faceplates with their lateral flange portions 11 and 12, respectively, directed outwardly and terminating approximately flush with the margins of the face-plates. The face-plates are folded back or returned at their margins so asto embrace the edges of the channelshaped members 11 and 12,as indicated clearly at 14 and 15, respectively, thus forming at the margins of the sash flange-like extensions (designated as a Whole 16 16 and 17 17) of three-ply strength. The'top side member of the sash 13 is formed in the shape of a cap which telescopes over the upper margins of the face-plates and is removably secured in place. To this end a filling-block 18 is fitted within the hollow top-rail thus formed,which filling-block is secured rigidly in position with its upper surface flush with the top edges of the face-plates by means of screws inserted in said face-plates,as indicated in dotted lines at 19, and the cap member 13 is in turn secured to the filling-block by means of other screws, as indicated in dotted lines at 20. The overlapping flange members-S, which form the outer sides of the glass-receiving channel or recess, are omitted across the top side of the sash, as best indicated in Fig. 2, so that when the top cap 13 and filling-block 18 have been removed the glazing may be inserted in position. Fig. 5 shows a detail cross-sectional view of one of the stile members in the form in which it leaves the first pair of formingdies, the outer returned flange portion 14 or 15 being only partially bent to its final shape, and likewise the inner marginal portions 7 and 8 being but partially formed. By subsequent forming operations these parts are formed into their final shape in a well-understood manner.

In Fig. 4 we have shown a slight modification, in which instead of forming the parts 7 and 8 of theglass-receivingchannel integrally with the face members a separate channel member 21 is provided,which is constructed to fit between the parallel flange portions 6 of the face members, and said channel member is provided with returned portions 22, which embrace or are folded upon said flange portions 6. In other respects the construction is or may be identical with that first described. The exact cross-sectional form of the face members shown, in Fig. 4 is shown in detail Fig. 6, it being understood that Fig. 6, like Fig. 5, shows the face member in the form in which it leaves the first pair of forming-dies.

The assemblement of the several sash members is entirely obvious and need not, therefore, be described in detail.

It will be understood from the foregoing description that a sash-frame embodying our invention may be constructed in the most economical manner, since the die operations by which the chief members of the frame are formed are extremely few and simple, and it will be further understood that a frame thus constructed is entirely free from external seams, which would tend to render the structure unsightly and are objectionable both because they must be sealed with solder to render the structure weatherproof and because they are expensive it riveted or clenched, so as to be fireproof. It will be noted that the construction is such thatthe sash-frame presents finished edges both around the glazing and its outer edges, thus not only enhancing the appearance of the frame, but rendering it smooth and capable of moving freely within the window-casing. It is still further to be noted that a sash-frame made in accordance with the present invention is bound to be accurate as to its angles and finished form, thus obviating the inaccuracies due to handwork and to assembling a plurality of parts, which as heretofore constructed have unavoidably been more or less inaccurate.

While we have shown and described herein what we deem to be a preferred embodiment of the invention, yet the details of construction may obviously be modified Without departing from the spirit of the invention, and we do not, therefore, limitourselves to the details of construction shown, except to such extent as they are made the subject of specific claims.

We claim as our invention 1. In a sheet-metal window-sash, a sash face member struck up from a sheet of metal to form top, bottom and side stile members integrally united and constituting one side of a sash-frame of .circumferentially-uninterrupted continuity, the inner margins of said frame members being formed to extend to, and terminate in, a plane parallel with, but removed from, the face plane of the sash, and channel-forming flange portions connected with said inner margins to receive the edge of the glass, substantially as described.

2. In a sheet-metal window-sash, a sash face member struck up from a sheet of metal to form top, bottom and side stile members integrally united and constituting one side of a sash-frame of circumferentially-uninterrupted continuity, the inner margins of said frame members being formed to extend to, and terminate in, a plane parallel with, but removed from, the face plane of the sash, and channel-forming extensions formed integrally with said inner margins, said channel-form:

ICS

ing extensions comprising a returned portion arranged to extend parallel with the general plane of the sash, and a marginal portion bent at right angles to said returned portion, as and for the purpose set forth.

3. In a sheet-metal window-sash, the combination with a pair of reversely-formed sash face members, each struck up from a sheet of metal to form top, bottom and side stile members integrally united, the inner margins of said stile portions being formed to extend ob,- liquely inwardly and toward each other and terminatingin channel-forming portions, and top, bottom and side stile members formed independently of said face members, and extending between, and uniting the latter, at or near the outer margins thereof to form a hollow construction.

4. In a sheet-metal window-sash, the combination with a pair of reversely-formed sash face members, each struck up from a sheet of metal to form top, bottomand side stile members integrally united, the inner margins of said stile portions being formed to extend obliquely inwardly and toward each other and terminating in channel-forming portions, and

top,- bottom and side wall members formed sheet of glass or analogous glazing supported 40 between said face-plates, the inner margins of said face members forming the boundaries of the sash-opening being extended from the outer face plane of the sash obliquelyinwardly to, and engaging the respective sides of the glass, and forming in conjunction with the latter acompletely-closed hollow sash-frame, substantially as described.
